A further dump of Sony Pictures corporate secrets appears to have been put on the Internet over the weekend, with hackers warning of more to come.

A message pointing to 5 gigabytes of data was posted to the Pastebin website and signed by GOP. Thats presumably the same "Guardians of Peace" group or person that claimed responsibility for the Sony Pictures hack.

"We are preparing for you a Christmas gift," said the message. The gift will be larger quantities of data. And it will be more interesting. The gift will surely give you much more pleasure and put Sony Pictures into the worst state.

The message asked Sony to send an email to one of five anonymous addresses "to tell us what you want in our Christmas gift."

The files carried the same password as previous releases and were entitled "My Life At The Company - Part 2."

The post was subsequently removed from Pastebin.

It pointed to five websites hosting BitTorrent tracker files, which are used by BitTorrent software to locate files on the global file-sharing network. Several of the sites hosting the tracker files appear to have removed them.

It was not immediately possible to determine the contents of the files in the latest data dump.

Sony Pictures was hacked in late November and has had to endure two weeks of embarrassing leaks of corporate information onto the Internet.

The major Hollywood movie studio first saw several unreleased movies uploaded then salary information about its employees. Leaks have also included medical information about employees, financial data, contracts for TV shows and, last week, the Outlook email boxes of two senior executives. Those email leaks revealed embarassing message exchanges with executives at Sony and other Hollywood studios.
